The answer is: " 32a² − 24a − 8 " .
__________________________________________________
Given:
__________________________________________________
(8a − 8)(4a + 1) ; Let us expand this expression using the: "FOIL" method.
___________________________________________________
"FOIL" stands for "<u>F</u>irst terms, <u>O</u>uter terms, <u> I</u>nner Terms, <u>L</u>ast Terms" ;
in that order.
___________________________________________________
Basically:
_______________________________________________________
(a + b)(c + d) = ac + ad + bc + bd ;
in which the:
<u>F</u>irst term is: "ac" ;
<u>O</u>uter term is: "ad" ;
<u>I </u>nner term is: "bc" ;
<u>L</u>ast term is: "bd " .
__________________________________
So; we have (given):
(8a − 8)(4a + 1) ;
__________________________________________________
Let's take the "<u>F</u>irst, <u>O</u>uter, <u> </u><u>I</u>nner, and <u>L</u>ast terms" ; as follows:
__________________________________________________
<u>F</u>: (8a)*(4a) = 32a² ;
__________________________________________________
<u>O</u>: (8a)*(1) = 8a ;
__________________________________________________
<u>I </u>: (-8)*(4a) = -32a ;
__________________________________________________
<u>L</u>: (-8)*(1) = -8
__________________________________________________
Now, let us write out these terms:
__________________________________________________
32a² + 8a − 32a - 8 ;
__________________________________________________
Now, combine the "like terms" in this expression; to simplify:
+ 8a − 32a = -24a ;
__________________________________________________
and rewrite the simplified expression ; which is:
__________________________________________________
32a² − 24a − 8 .

Step-by-step explanation:
There are 2 red, 2 blue, 1 orange, 2 purple and 3 green stones. = 10
P( green) = number of green / total
= 3/10
Answer:
the table goes
9.25, 18.5, 27.75, 37, 46.25, 55.5, 64.75, 74, 83.5
1: greg makes 18.5 (or 18.50) an hour. I got that by taking the 64.75 we know and dividing it by 3.5.
2. if greg works 60 hours he will have made 1,110$. he made enough money for the lawn mower.
Answer:
1/2=x
0.5
Step-by-step explanation:
x will be the number
5/100=(1/10)x
5/10=x
1/2=x
1/2=0.5
